Tanacetum parthenium
Also called Feather Leaved Tansy, Featherfew, Common Feverfew
Feverfew is a bushy, daisy-flowered perennial in the daisy family, grown in gardens for its white and yellow flowers and aromatic leaves. It spreads readily by seed, so deadheading helps keep it in check.
Tanacetum parthenium, known as feverfew, is a flowering plant in the daisy family, Asteraceae. It may be grown as an ornament, and may be identified by its synonyms, Chrysanthemum parthenium and Pyrethrum parthenium. Having its origin in the Balkans region, it is now distributed worldwide.
Although long used in traditional medicine, there is no clinical evidence that it has any therapeutic effects.
Feverfew is native to Eurasia, specifically the Balkans, Anatolia, and the Caucasus, but cultivation has spread it around the world.
A perennial herb, it favors full sun 38 to 46 cm (15–18 in) apart. It grows up to 70 cm (28 in) tall. It is hardy to USDA zone 5 (−30 °C or −22 °F).
